This is the transcript of the talk I heard that told me about Blue Brain:
"It's called the Blue Brain project in Switzerland. They have combined many different types of technologies and what they have done is they have essentially created a type of MRI that can scan the entire brain. All of the intricate structures of the brain itself and what they have discovered is that some of us and have in our brains fourth, fifth, sixth dimensional structures already. There are other people that have seven, eight, nine dimensional structures in their brain. You're a third density physicality and yet in your brain you have multiple dimensional structures!"
I always come back to the book https://en.wikipedia.org/wiki/Flatland and try and grok that hey, maybe dark matter we observe here in 3d is just stuff from these weird other directions a flatlander wouldn't understand.
